SIDNEY HENRY, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE UNITED STATES ARCGAS COMPANY, OF NE\V JERSEY.

GAS BURNER.

SPECIFICATION forming part of Letters Patent lilo 385,669, dated July 3,1888.

Application filed December 8, 1887. Serial No. 257,346. (No model.)

To all whom it may concern:

Be it known that I, SIDNEY HENRY, a subject of the Queen of GreatBritain, residingin the city of Chicago, county of Cook, and State q ofIllinois, have invented certain new and use ful Improvements inGas-Burners, of which the following is a full, clear, and exactspecification.

My invention relates to that class of burners wherein the gas issuperheated previous to its consumption,and which devices are moregenerally known as regenerative lamps.

The object of this invention is to provide a means by which the gas maybe superheated to any desired extent without being subject to thedisadvantages which naturally accrue to many of such lamps by reason ofthe carbon depositing itself in and around the gas chamber and burnerand in the course of time clog- 2o ging up the same so that the flamebecomes uneven and irregular, and many regenerative lamps have for thisreason only partially and quite imperfectly fulfilled the intentions oftheir originators.

In order that my invention may be more fully understood, I will nowdescribe it with reference to the accompanying drawings, which serve toillustrate the same, and in which Figure l is a vertical sectional'viewof my improved lamp. Fig. 2' is a lateral section taken on the line X X,Fig. 1.

A is a cylinder, which forms a flue or central draft, into the lower endof which is secured, by means of a bayonetjoint, B, a small cylinder, 0,preferably composed of terracotta or any other suitable material..

D and E are respectively air and gas chambers contained in an outerbellshaped covering, F, the former cylinder being formed by anoutwardly-swelled portion in said bell, and the ring or flange G, whichis supported in said bell by means of the four arms H, as shown. Thelatter chamber, D, is composed by a ring-shaped box having the do w n- 5wardly projecting mouth I, and it is supported by the centraldraft-tube, A, by means of three lugs, J, which rest upon the flange Kon the lower end of said tube, there being sufficient space between saidtube and the chamber o for a free passage of air.

Extending downwardly through the bell F is the gas'supply pipe L, whichis secured in the top of the chamber E, and admits gas to a supplementalchamher in the top of the said chamber E, which supplemental chamber isformed by a perforated plate, N. Stuffed in this chamber E, below theplate N, is a suitable quantity of as bestus, M, or other suitablenon-combustible material, through which the gas on leaving thesupplemental chamber is filtered,and thus deprived of theobjectionableingredients. It will be seen that by this arrangement twoimportant objects are obtained. First, instead of hithertounsatisfactory and easily-clogged perforated burners, I have produced anoutlet or burner of a circular form without perforations and capable ofbeing easily reached for cleaning by simply loosening the insidecylinder, 0, by means of the bayonet-fastening before referred to. Theprincipal object of the chamber E is to cause the gas to pass throughthe layer of asbestus or other suitable porous and non combustiblematerial, which will act as a filter for the gas, and will cause the gasto be superheated by reason of the slowness with which the latterpermeates the said porous material. To the lower end of the bell may besecured by any suitable means a globe of any well-known or applicableshape.

I do not claim this particular construction of lamp, as it will bereadily seen that this form of burner and the insertion of a known noncombustible porous like material in a chamber specially provided forthat purpose could be adapted to any of the lamps now be fore thepublic.

In the drawings an inverted flame is shown. This may be reversed bymeans well known and within the knowledge of every mechanic. The flamemay also, by a reversal of the relative position of the flue Aand itsinternal cylinder, G, be made to burn up from the outer circumference ofthe flue A and into the internal cylinder in a downward direction. 9

Having thus described myinvention, the following is what Iclaim as newtherein and do sire to secure by Letters Patent:

In a regenerative gas-burner, the combination, with the centraldraft-tube, the gas-sup- 10o ply pipe, and an annular chambersurrounding said tube and having connection with said gas-supply pipe atits top, and haviuga burner around its bottom, of an annular filling ofa 5 porous fibrous non-combustible substance in said chamber, and aperforated plate resting upon said substance and forming a supplementalchamber for the distribution of the gas before passing through thefilling, essentially as shown and described.

It is hereby certified that in Letters Patent No. 385,669, granted July3, 1888, upon the application of Sidney Henry, of Chicago, Illinois, foran improvement in Gas Burners, the name of the assignee was erroneouslyWritten and printed United States Are Gas Company, whereas said nameshould have been Written and printed United States Are Gas Lamp Company;and that the proper correction has lieen made in the files and recordspertaining to the ease in the Patent Offioe, and should be read in theLetters Patent that the same may conform thereto.
